RamCompare Update

RamCompare is an innovative
project which aims to enable the UK sheep industry to drive genetic improvement
forward through the inclusion of commercial data in genetic evaluations.
Partners from right along the supply chain are involved and extensive data
recording, from birth to slaughter, is being carried out over a two-year period.
Bridget Lloyd, RamCompare project co-ordinator, gives an update on how the
project is getting on.

It has been a busy yet successful year so far for RamCompare
and that’s set to continue as we enter into the second breeding season.

This spring we had a bumper crop of lambs, with over 3,600
born from 39 different sires across the six project farms. Growth has been
closely monitored in the following months, with the collection of birth, eight week,
90 day and sale weights. A huge amount of data has been generated which is currently
being entered into the Signet Breeding Services database. Initial analysis will
take place over the autumn and winter months and so far we are really pleased
with the results coming through.

Lambs have been selected for slaughter fortnightly since May
and have been processed through either Dunbia or Randall Parker Foods, as part
of Sainsbury’s Producer Group. This activity will be drawing to a close soon,
with the last group of lambs being processed in November. Saleable meat yield
data has been collected from a proportion of female lambs in each sire group
and further tenderness testing will now start on loins from this subgroup.

In other news, the second breeding season has begun and we
have some great rams joining the project this year. All have estimated breeding
values (EBVs) in the top 20 per cent for their breed and provide variety to
rams already on test. 24 new, natural service sires have been selected with
four placed on each of the six RamCompare farms. These sires will work
alongside some of the rams selected last year who will be used for a second
season to provide linkage between the years.

A further five rams have been chosen for artificial
insemination (AI) and they complement those selected last year, many of whom
will be used again this season. Details of all the rams can be found on the
Signet website.

A total of 68 rams will be tested over the duration of the
project and full analysis of results will be made available from November 2017.
Top 25 lists will be produced for rams on test for eight-week weight, scan
weight, muscle depth and fat depth EBVs. From the results, new EBVs will be
developed for days to slaughter and carcase value and these lists of rams will be
published in November 2017.If you are interested in an update of the project and seeing
some of the rams at work, we are holding an event at Thistleyhaugh Farm, on
Wednesday 3 November 2016 in Long Horsley, Northumberland and it would be great
to see you there. For more information, email brp.events@ahdb.org.uk or ring the
events office on 01904 771211.

Finally, we have a great opportunity for pedigree producers
to access semen from some of our RamCompare sires. The aim is to build genetic
linkages between Signet recorded flocks and the RamCompare project. The semen
is available free of charge, conditions apply. For more information email
bridget.lloyd@ahdb.org.uk

More information on the project and our trial farms can be
found on the Signet website.
